[OpenLayers-Users] OpenLayers.Layer.WMS - using SVG Format?

Mon Dec 17 10:09:25 PST 2012

Due to the way that IE8 handles SVG, I strongly doubt there is a easy 
clean solution for your problem if you must support IE8.
One option would be to force iframe tiles for the layers you want to use 
SVG for in IE8.

See the description of how to do this in the deprecation note for the 
old WMS.Post layer
https://github.com/openlayers/openlayers/blob/master/lib/deprecated.js#L1884

set 'maxGetUrlLength' to some small number for the desired WMS layers if 
you can detect that you are on IE8

I can just use a standard <html> tag without doctype and the svg layer displays properly within Google Chrome, Firefox or Safari. When I use the same code within IE8 I am getting the invalid pink tiles, but when right-clicking and pasting the request into the browser as -
